Florida theater shooting suspect Curtis Reeves is lonely but confident that his self-defense claim will result in his acquittal, according to jailhouse phone calls released by the state attorney's office.

According to CNN affiliate, Bay News 9, the 71-year-old, who is being held without bail on a second-degree murder charge, also tells his daughter he's concerned about the family's finances.

"I'm more worried about you all than I'm worried about me," he says.

"And we're more worried about you than we are worried about us," Jennifer Shaw, his daughter, responds.

In January, Reeves and his wife were attending a showing of "Lone Survivor" at a Wesley Chapel movie theater. Reeves left the theater to report to management that the man in front of him, Chad Oulson, was texting during the previews. When he returned the two exchanged words.

Video from the scene appears to show Oulson snatching Reeves' popcorn off his lap and throwing it at him. Reeves responds instantaneously with a single, fatal gunshot. A preliminary hearing suggested the case will come down to whether a jury believe Reeves was intimidated by Oulson and acted in self-defense, or if Reeves overreacted to Oulson texting.

In the jailhouse tapes, Reeves tells his daughter she can sell some of the family's belongings if necessary.

"If we need money, sell the motorcycle, motorcycle trailer, the kayaks, the trailer and --"

Shaw cuts him off: "We have all that under control. We're not even going to talk about it. Don't waste your time."

In another moment captured on tape, his young granddaughter greets him with a "Hi!"

"Hey sweetheart, this is Pawpaw. Pawpaw loves you," Reeves said.

"Can you tell grandpa 'I love you'?" Shaw asks the child. Her age is not clear, but her voice is that of a very young girl.
